there is ZERO proof that hcg helps increase sperm count.  ZERO.  ZERO ZERO
if it did it would have been marketed for that a long fucking time ago cause the shit has a huge margin of profit.  there is NOTHING out there that has ever been approved as a fertility drug for men!!  anyone who says otherwise is a fucking liar 
what HAS shown to increase sperm count is clomid + vitamin E.  this was shown in studies, but there isn't enough yet to proclaim that as a fertility protocol 
my advice to you is if you want to have the most ammunition avoid steroids
